guiding question

[blinky]

Since I am now autoguiding I would expect when stacking my images that the values for the offset and angle were 0 as the guiding should be keeping the camera pointing at the same piece of sky?

Just stacking some subs from last night and there is a small affset of a couple of pixels on each one, the ange though seems to be staying at 0. If it is that I am not properly polar alinged and it is camera rotation I would have thought that the angle and not the offset would change by a small amount each time

Thats flexure between the guide scope and the imaging scope... something I`m trying to eliminate from my system

thats interesting, i thought my guide scope was pretty solid. Will need to reinvestigate.
